>where we disagree is that you seem to think those differences
_matter_, in some important way.  they don't matter.  at least
not in the example i provided.  not in the slightest.  not at all.

That these issue “matter” is simply confirmed by trying to read the generated ebook file formats from PG many if not most of which fail in pretty spectacular ways on real world ebook reader devices. Even “simple” things such as paragraphs are frequently handled poorly. Yes, in general, the ebooks are “readable”, but garbage is splayed around everywhere needlessly, especially when “expert” html authors start trying to get cute.

Maybe you’re happy to say “Oh well, it’s still *readable*” – but I’m not.
